Electronic contracting is an essential service to develop electronic commerce. But this service is not very used because merchants and consumers do not trust in contracting by electronic means. For time we already have technical solutions that should allow to give trust to the actors implied in this new scenario. But the lack of international standards and of an appropriate juridical mark, supp...

The principal aim of this paper is to estimate a stochastic frontier cost function and an inefficiency effects model in the analysis of the primary health-care services purchased by the public authority and supplied by 180 providers in 1996 in Catalonia. The evidence from our sample does not support the premise that contracting out has helped improve purchasing cost efficiency in primary care. ...

We show that strongly contracting geodesics in Outer space project to parameterized quasigeodesics in the free factor complex. This result provides a converse to a theorem of Bestvina– Feighn, and is used to give conditions for when a subgroup of Out(F) has a quasi-isometric orbit map into the free factor complex. It also allows one to construct many new examples of strongly contracting geodesi...
